Elektrogas Manual Reset Solenoid Valves (Gas) EVRMNA

Features:

• The valves are made of aluminum alloy die-cast (or hot-pressed brass for OT versions), with a wide range for inlet/outlet connections from DN10 up to DN 300.
• Sealings are made of NBR-based rubber certified for use with gas (EN 549).
• Suitable for use with air and non-aggressive gases included in the 1, 2 and 3 families (EN 437).
• Special versions suitable for aggressive gases, free of non-ferrous metals and with FPM seals.
• Pipe connections meet Group 2, according to EN161 requirements.
• The whole range can be provided in Ex-proof execution, for use in Zones 2 and 22, according to 2014/34/EU Directive (ATEX).
• Two range of operating pressure: low pressure (0…600 mbar) and medium pressure (0…6 bar).
• The kind of valves are normally not powered allowing a remarkable energy saving.
• An incorporated fine mesh filter protects the valve seat and disc as well as downstream components and prevents dirty contamination (except brass models).
• Provided with 1/4” pressure gauge on two sides in the inlet chamber (except brass models), to connect manometers, pressure switches, leakage tester or other gas equipments. Flanged models are provided with gauges also in the outlet chamber.
• The encapsulated coil is provided with ISO 4400 plug and suitable cable gland to avoid water and dirty contamination, allowing a safe outdoor installation.
• All components are designed to withstand any mechanical, chemical and thermal condition occurring during typical service. Effective impregnation and surface treatments have been used to improve mechanical sturdiness, sealing and resistance to corrosion of the components.
• Valves are 100% tested by computerized testing machineries and are fully warranted.
